When to switch to WebP
If you control the site or app where an image will be shown, WebP is almost always the right choice — smaller files, the same visible quality, and full browser support. Converting an existing library of JPGs and PNGs to WebP is one of the cheapest ways to speed up a page and improve Core Web Vitals.
The exception is handing a file to a third party. Marketplaces, government portals and some email clients still expect JPG or PNG, so keep those as they are and reserve WebP for images you serve yourself.
Frequently asked questions
- Why is WebP smaller than JPG or PNG?
- WebP uses more modern compression than JPG and supports transparency like PNG. At matching visual quality it typically produces files 25–35% smaller than JPG, which is why it is the default image format for the modern web.
- Can I convert JPG or PNG to WebP here?
- Yes. Drop in JPG or PNG files and choose WebP as the output format — the tool re-encodes them as WebP, which is usually much smaller. This is the fastest way to bulk-convert a folder of images to WebP.
- Does every browser support WebP?
- Every current browser — Chrome, Safari, Firefox and Edge — displays WebP. The only place to avoid it is a system that explicitly requires JPG or PNG, such as some older upload forms; for those, choose JPG output instead.
- Are my images uploaded to a server?
- No. Compression runs entirely in your browser. Your files are processed on your own device and never transmitted anywhere.
